APPENDIX C - MMEL AND MEL PREAMBLE
PREAMBLE
The following is applicable for authorized certificate holders operating underCASR Parts 121, and 135: CASR require that all equipment installed on anaircraft in compliance with the Airworthiness Standards and the OperatingRules must be operative. However, the Rules also permit the publication of aMinimum Equipment List (MEL) where compliance with certain equipmentrequirements is not necessary in the interests of safety under all operatingconditions. Experience has shown that with the various levels of redundancydesigned into aircraft, operation of every system or installed component maynot be necessary when the remaining operative equipment can provide anacceptable level of safety.
The DGCA approved MMELs for aircraft which indonesia holds responsibilityas state of design, and MMELs accepted which have been approved by a foreignstate of design includes; those items of equipment related to airworthiness,operating regulations and other items of equipment which the DGCA finds maybe inoperative and yet maintain an acceptable level of safety. The acceptablelevel of safety may be achived by appropriate conditions and limitations; it doesnot contain obviously required items such as wings, flaps, and rudders.
The MMEL is the basis for development of individual operator MELs which takeinto consideration the operator's particular aircraft equipment configurationand operational conditions. Operator MELs, for administrative control, mayinclude items not contained in the MMEL; however, relief for administrative
control items must be approved by the DGCA. An operator's MEL may differ informat from the MMEL, but cannot be less restrictive than the MMEL. Theindividual operator's MEL, when approved and authorized, permits operation ofthe aircraft with inoperative equipment. Equipment not required by theoperation being conducted and equipment in excess of CASR requirements areincluded in the MEL with appropriate conditions and limitations. The MELmust not deviate from the Aircraft Flight Manual Limitations, EmergencyProcedures or with Airworthiness Directives. It is important to remember thatall equipment related to the airworthiness and the operating regulations of theaircraft not listed on the MMEL must be operative.
Suitable conditions and limitations in the form of placards, maintenanceprocedures, crew operating procedures and other restrictions as necessary arespecified in the MEL to ensure that an acceptable level of safety is maintained.
The MEL is intended to permit operation with inoperative items of equipmentfor a period of time until repairs can be accomplished. It is important thatrepairs be accomplished at the earliest opportunity. In order to maintain anacceptable level of safety and reliability the MMEL establishes limitations onthe duration of and conditions for operation with inoperative equipment.
AC-1
SI 8900 - 4.4
The MEL provides for release of the aircraft for flight with inoperativeequipment. When an item of equipment is discovered to be inoperative, it isreported by making an entry in the Aircraft Maintenance Record/Logbook asprescribed by CASR. The item is then either repaired or may be deferred perthe MEL or other approved means acceptable to the DGCA prior to furtheroperation. MEL conditions and limitations do not relieve the operator fromdetermining that the aircraft is in condition for safe operation with items ofequipment inoperative. When these requirements are met, a MaintenanceRelease, Aircraft Maintenance Record/Logbook entry, or other approveddocumentation is issued as prescribed by CASR. Such documentation isrequired prior to operation with any item of equipment inoperative.
Operators are responsible for exercising the necessary operational control toensure that an acceptable level of safety is maintained. When operating withmultiple inoperative items, the interrelationships between those items and theeffect on aircraft operation and crew workload will be considered. Operatorsare to establish a controlled and sound repair program including the parts,personnel, facilities, procedures and schedules to ensure timely repair.
WHEN USING THE MEL, COMPLIANCE WITH THE STATED INTENT OF THE
PREAMBLE, DEFINITIONS, AND THE CONDITIONS AND LIMITATIONSSPECIFIED IN THE MEL IS REQUIRED.
